objective(s): tuberculosis is one of the most important infectious diseases with high mortality rates worldwide, especially in developing countries. interleukin17 (il-17) is an important acquired immunity cytokine, which is mainly produced by cd4+th17 cells. it can recruit neutrophils and macrophages to the infected site in the lungs. il-23 is one of the most important inducers of il-17. in the...
screening is one of the ways to combat tuberculosis (tb) and should be mostly concentrated on groups showing some symptoms of the disease. tuberculosis can be transferred from person to person in laboratories, prisons and psychiatry hospitals. the purpose of this study was to survey pulmonary tb in patients with schizophrenia in rasht.in this descriptive-cross sectional, two hundred fifty seven...
A 55-year-old physician had a PPD made as part of a clinical evaluation. Laboratory tests were unremarkable and PPD, read in 48 hours, showed an area of induration of 18 mm and an erythema of 51 mm (Panel A). A 2 mm punch biopsy was done in the center of the induration 96 hours after the injection. Histopathology showed an intense perivascular cuffing with macrophages and lymphocytes and edema ...
Quinidine derivative (QD)(2)PYR was found to catalyze the asymmetric direct amination of unprotected prochiral 3-oxindole with DIAD to construct quaternary stereocenters at the C3 position with excellent enantioselectivity.
A kinematic approach was used to measure mother-infant spatial proximity at 4 months. Maternal postpartum depression (PPD) impacts on mother-infant spatial interaction. We compared 28 dyads with mothers meeting criteria for PPD and 46 typical dyads. The PPD dyads had less variability in spatial proximity compared to typical dyads.
Tuberculosis is an important health problem in developing countries and the BCG vaccine plays an important part in preventing the disease. There are different reports about the preventive value of BCG. Some of them claim that it is satisfactory while others suggest that it provides little protection. There are also varying ideas about the optimum time to vaccinate babies, some studies suggestin...
BACKGROUND The possible association between (tuberculous and nontuberculous) mycobacterial infections and sarcoidosis is still a matter of dispute. Using diagnostic tests for specific T-cell responses, this association can be investigated in an innovative manner. OBJECTIVE To measure the T-cell responsiveness to the purified protein derivative (PPD) antigen in blood and broncho-alveolar lavag...
LANDI, S. (University of Toronto, Toronto, Ontario, Canada), AND H. R. HELD. Physicochemical and biological studies on various preparations of tuberculin purified protein derivative. Appl. Microbiol. 13:132-139. 1965.-Tuberculin purified protein derivative (PPD) has been prepared by seven different precipitation methods from culture filtrate of Mycobacterium tuberculosis var. hominis. It was fo...
